  • Fig. 10 is a block diagram of a modification of a cordless facsimile apparatus of the second embodiment.
  • This modification differs from the second embodiment in the signal conversion means 9 is included in the telephone function unit of the parent machine rather than in the facsimile function unit of the child machine.
  • the operation of the apparatus of this modification when a signal indicating a communication request is received from the public telephone line is the same as that of the above-mentioned apparatus of the first embodiment (See Fig. 2).
  • the operation of the apparatus at the time of initiating communication with the party to be called using the child machine is the same as that of the above-mentioned apparatus of the second embodiment (See Fig. 7).
  • Figs. 11A and 11B are flowcharts showing the operation of the apparatus of the above modification at the time of facsimile transmission.
  • the flowcharts in Figs. 11A and 11B differ from those in Figs. 8A and 8B in that the operation (step S195) of converting picture signals read from a document into analog signals is performed immediately after the operation of demodulating radio signals (step S200) rather than immediately after the operation of reading a document (step S194).
  • Fig. 12 is a flowchart showing the operation of the apparatus of the above modification at the time of facsimile reception.
  • the flowchart in Fig. 12 differs from that in Fig. 9 in that the operation (step S243) of converting analog picture signals into digital signals is performed immediately after the picture signals are received from a public telephone line (step S237).
  • Fig. 13 is a block diagram of a cordless facsimile apparatus of the third embodiment of the present invention. Parts of Fig. 13 which have the same function as that of parts of Figs. 1, 6, and 10 are given the same reference numerals, and the explanation thereof is omitted.
  • both the parent machine and the child machine have the facsimile function units designated by reference characters B and B', respectively.
  • the user selects the child machine by using the operation means 10 of the facsimile function unit of either the parent machine or the child machine.
  • the operation of the apparatus of the third embodiment at the time of facsimile transmission from the child machine is the same as that at the time of facsimile transmission by the apparatus of the second embodiment (See Figs. 8A and 8B).
  • the operation of the apparatus of the third embodiment at the time of facsimile reception at the child machine side is the same as that at the time of facsimile reception by the apparatus of the second embodiment (See Fig. 9).
  • the user selects the parent machine by using the operation means 10 of the facsimile function unit of either the parent machine or the child machine.
  • the operation of the apparatus of the third embodiment at the time of facsimile transmission from the parent machine is the same as that at the time of facsimile transmission by the apparatus of the first embodiment (See Fig. 4).
  • the operation of the apparatus of the third embodiment at the time of facsimile reception from the parent machine is the same as that at the time of facsimile reception by the apparatus of the first embodiment (See Fig. 5).
